Authorities on Wednesday evening pulled the dead body of a male from the Des Moines River near downtown, police said.

Police and fire rescue crews responded at about 4:47 p.m. and pulled the body from the river just south of the Grand Avenue Bridge between downtown and the city's East Village neighborhood. Officials covered the body with a white sheet as detectives investigated the scene.

The body was discovered in the water by construction workers, police said. The county medical examiner is expected to examine the body Thursday, Sgt. Paul Parizek said.

Police expect to update the public about the investigation Thursday morning.
